Reduction of ethanoic acid with LiAIH4 produces?

Correct answer: C. Ethanol

  • A. Propanol
  • B. Ethanal
  • C. Ethanol
  • D. Ethane

Explanation

Option C is correct since the reduction is the addition of hydrogen to a compound. So when hydrogen is added to ethanoic acid, ethanol is produced. The -COOH group is changed to CH2OH. Option A is incorrect since propanol is the result of the reduction of propanoic acid. Option B is incorrect since ethanal can be produced via oxidation of ethanol. Option D is incorrect since ethane can be produced by the reduction of ethene.

About Carboxylic Acids

Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
